To all whom-#mcy y l Be it known that I', EMILE Azn, of Minneapolis,Hennepin county,l Minnesota, have invented certain new and usefulImprovewhich will allow t differentspeeds.

My invention consists generally in various constructions andcombinations, all as here inafter described. and out inthe claims.-

In the accompanying drawings, forming part of this s ec1flcation,.Figure1 is a sectionalview i ustratingthe construction o f particularlypointed the mechanism.' Fi 2 is .a sectional view` V on the line -x ofig. 1. Fig. 3 is a sectional view o n the line z-z of Fig. 1.- Fig. 4is` a sectional view on the line y-yof Fig. 1.

In the' drawing, 2 represents a sprocket wheel having lates ,3 and 4secured thereto by bolts 5 an inclosingthe o erating portion of themechanism. The p ates 3 and 4v have hubs `6 wherein axles 7 and-8 arey'ournaled and upon which the carrying w eels. are mounted in the usualway. At the inner ends of the axles 7 and 8 eccentrics 9 and- 10 areformed. A primary4 cross headv 11 .is mounted. to'slide 1n a guideway 12provided on the-sprocket 2, and the cross head 11 has 1gluideways 13 toreceive secondary cross eads 14 and 15'. The guideways 13 are at rightan les substantially to the guideways 12 and t e cross heads 14 vand 15move in a direction at ri ht angles to the direction of movement of t e4cross head 11. The cross heads 14 and 15 have openings 16 to receivethe eccentrics 9 and 10 and the revolution of the eccentrics Willcausethe cross heads 11,

14 and 15 to be reciprocatedin their uide- `4iways. The cross head 11isprovide with wheels and axles'to move A' in dependentlyof one anotherand operate at centrally pivoted, said levers having recesses 20 intheir ends to receivepins 21 carried b the cross heads 14 and 15'A andprovided wit 1 anti-friction rollers 22. The eccentrics vrevolve in thesockets 16 .and impart a reciprocating movement tothe cross heads 11, 14and 15. 4 One wheel-and its axle may turn faster than the op osite onesothat one ecbrackets 17 wherein'levers 18 and 19 are centric willoverta e the other, and to avoid dead centers when the eccentrics arepassing one another'thelevers 18 and 19 are oscillated 'to' move thecross heads 14 and 115, each I ever having a pivotal connection withboth cross heads.. With this mechanism independent movement of the"axles .or shafts 7 and 8 is permitted, and "if one 4axle moves fasterthan the other one the cross heads and levers will be operated tocompensate for the difference in travel.

I claim as my invention l 1.- A differential mechanism comprising a gearwheel, a casing secured thereto and havmg hubs,` axles journaled in saidhubs and primary cross headhaving a guideway in said gear, secondarycross heads havin guideways in said primary cross heads an( movable in adirection substantially at right angles' to the direction of movement ofsaid primary cross' head, said4 secondary cross The eccentrics ma bemade Iny varlous sizesaccordmg to the c aracter of the vehicle on Whlchthe device 1s yhaving eccentrics on their inner ends, a

eads having openings to receIvevv said eccentrics, and means whereby themovement of one secondary cross head .Will be transmitted to the otherone.

2. A' compensating mechanism comprising a gear Wheel having a guidewaytherein, a prlmary cross head adapted to slide in said guideway 'andhaving uideways at right angles substantially to t e guideway in saidgear wheel, secondary cross heads fitting Within said secondaryguideways and having .openings therein, plates secured to said gear andlncloslng said cross heads, axles ]ourl naled in said plates and havingeccentrlcs to enter the openings in saidsecondary crossl heads,l andlevers centrally pivoted on said In vWitness whereof, I have hereuntoset primary cross head, each lever having a piv my hand this 18th' dayof April 19,08*. n y o tal connection atone end with one'of said EMILEsecondary cross heads and a corresponding t v y l 5 connection at itsother end with the other oftv Witnesses: l
